Miniature Ball Bearings In Pillow Block Housing

Micromech has introduced a range of mounted miniature ball bearings designed for use in efficient and cost-effective applications in a variety of instruments and mechanisms. The Spyraflo mounted, miniature ball bearings meet the increasing demands of design engineers for an economical and precision bearing mounting method for smaller shaft sizes. The Spyraflo product consists of stainless-steel ABEC 3 precision Japanese-made ball bearings mounted in a precision-machined, sintered aluminium pillow block housing.

They are initially offered as non-aligning types as they are designed primarily for use in more precise applications. These miniature ball bearings will be offered in both inch and metric sizes from 4mm to 10mm shaft diameters, double-shielded bearings that are pre-greased for life. The aluminium body and stainless steel, together with the double shield, give the bearings a level of corrosion resistance that makes them suitable for food and wash down applications.

When previously considering the use of miniature bearings for an assembly, one of the critical design elements was precisely how the bearings could be mounted.

Typically the mount had to be precision machined, particularly when using high-performance miniature bearings. Spyraflo bearings are claimed to eliminate this task effectively and economically. The miniature bearings are especially suitable for the medical, pharmaceutical, scientific and other precision-oriented fields as they eliminate any need for designing, manufacturing or assembling precision mounts. Simply screw the pillow blocks in place to mount.
